Wipro — not receiving experience letter with roles and responsibilities

Hello,

My brother had worked with wipro for 3 years in benefits division. He left the organization in 2019 for further studies in canada for pgdm.

Now for applying for pr, he is fulfilling all the requirements, however, the canada government needs the experience letter that will include roles and responsibilities on the letter head along with mentioning he worked full time with them. I fail to understand how difficult it is for an organization to fulfill all these requirements for a colleagues who have worked for them passionately for 3 year. He is being sending emails to different email address provided by his manager but no one is helping. Please advise what should be done.

If he will not submit this form, he won't be able to apply for pr in canada. We have already spent a lot of money and my brother have got great score in ielts. Let's help in getting this document to him before it's too late.
Not sure how to get this document from wipro. We are tired of reaching out to them.
